The utility model discloses a slips need not to restore and can be to the size range who has improved the centre gripping drilling rod, the life cycle of extension drilling rod.
Description
Technical Field
The utility model relates to a preceding holder technical field especially relates to a holder before rig.
Background
After an internal marketization assessment system is established by a gas extraction team, innovation is continuously carried out, the requirements of internal marketization of mine response industry companies are met actively by improving improved equipment, optimizing engineering processes, repairing old and utilizing waste and the like, source-opening throttling is carried out, in the daily maintenance process of a drilling machine, the fact that a rubber cylinder of a ZDY-3200L drilling machine is frequently replaced, the frequency of the slip welding of a front clamp is high, the gap between the clamp and the drilling rod is too large after the drilling rod is abraded to phi 70mm, the clamping of the drilling rod cannot be carried out by the clamp, and the service cycle of each set of drilling rod is about 1 year.
To this end, we propose a drill front holder that solves the above mentioned problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving among the prior art the restoration rate of pressing from both sides the slips before the rig is high, lead to the short problem of drilling rod life cycle of its centre gripping, and the holder before the rig that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a holder before rig, includes an annular section of thick bamboo, fixedly connected with oil pipe on the annular section of thick bamboo inside wall, the inboard fixed mounting of an annular section of thick bamboo has a plurality of hydraulic piston, and is a plurality of hydraulic piston all is linked together with oil pipe, and is a plurality of the equal fixedly connected with slips of one end that oil pipe was kept away from to hydraulic piston, oil pipe's the left and right sides is equipped with oil inlet and oil-out respectively, oil inlet and oil-out are all fixed and run through the setting of an annular section of thick bamboo.
Preferably, the slips are conical slips, and a plurality of slips are matched.
Preferably, the hydraulic piston is a single-cone piston.
Preferably, the stroke of the hydraulic piston is 10 mm.
Preferably, a plurality of said hydraulic pistons are distributed in a uniform array inside the annular cylinder.
Preferably, valves are arranged on the oil inlet and the oil outlet.
Preferably, one end of the slip, which is far away from the hydraulic piston, is fixedly connected with a non-slip mat.
Compared with the prior art, the beneficial effects of the utility model are that:
the improved holder consists of a single-conical-surface piston and a conical-surface slip, hydraulic oil enters the piston through an oil pipe, the piston acts on the slip, a rubber cylinder is not used, the stroke of the single-conical-surface piston is 10mm, the novel holder can be suitable for drill rods between phi 73mm and phi 65mm, and the service life of the drill rods is prolonged to 2 years.
The utility model discloses a slips need not to restore and can be to the size range who has improved the centre gripping drilling rod, the life cycle of extension drilling rod.
Drawings
FIG. 1 is a perspective view of a front holder for a drilling rig in accordance with the present invention;
fig. 2 is a perspective view of a hydraulic piston in a front holder of a drilling machine according to the present invention.
In the figure: the hydraulic oil pump comprises an annular cylinder 1, an oil pipe 2, a hydraulic piston 3, a slip 4, an oil inlet 5, an oil outlet 6, a valve 7 and an anti-slip pad 8.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a front gripper of a drilling machine, including an annular cylinder 1, fixedly connected with oil pipe 2 on the inside wall of the annular cylinder 1, a plurality of hydraulic pistons 3 are fixedly installed on the inside wall of the annular cylinder 1, concretely, the hydraulic pistons 3 are single-cone pistons, the stroke of the hydraulic pistons 3 is 10mm, the plurality of hydraulic pistons 3 are all communicated with the oil pipe 2, the plurality of hydraulic pistons 3 are uniformly distributed on the inside of the annular cylinder 1 in an array manner, the one ends of the plurality of hydraulic pistons 3, which are far away from the oil pipe 2, are all fixedly connected with slips 4, concretely, the slips 4 are conical slips, the plurality of slips 4 are matched, the left side and the right side of the oil pipe 2 are respectively provided with an oil inlet 5 and an oil outlet 6, the oil inlet 5 and the oil outlet 6 are all fixedly arranged through the annular cylinder 1, it needs to be explained that valves 7 are respectively arranged on the oil inlet 5 and the oil outlet 6, it is worth mentioning that, one end of the slips 4, which are far away from the hydraulic pistons 3, is fixedly connected with a non-slip mat 8.
The utility model discloses in, drive four hydraulic piston 3 through 5 oil inlets of oil inlet and remove, hydraulic piston 3 drives the slips and removes, until will need the drilling rod of centre gripping fixed can.
The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
